In this example, after the mask shell 1 is fastened on the face, a sufficient ventilation space is formed between the mask shell 1 and the mouth and nose, and the mask shell 1 can be tightly attached to the face.

The endoscopic anaesthetic mask provided by the present application may comprise a variety of models, for example: no. 0, applicable to neonates; number 1 is applicable to infants; number 2 is suitable for children; number 3 is suitable for adult trumpet; number 4 applies to adult medium; the No. 5 is suitable for adult large-size patients and the like, the appearance of the endoscope anaesthetic mask of each model is similar, the endoscope anaesthetic mask can be enlarged or reduced in the same proportion, and the size of the endoscope cannula port can be specifically set according to the model of the endoscope anaesthetic mask, and is specifically shown in the table 1.

TABLE 1 parameters of different types of speculum anaesthetic masks

As shown in fig. 1, the gas inlet 3 is disposed at the highest point of the mask shell 1, and is a cylindrical pipe, and the cylindrical pipe of the gas inlet 3 is disposed outside the mask shell 1, is adapted to a standard ventilator pipe, and can be connected to a simple respirator or an anesthesia machine, or a respirator.

As shown in FIG. 1, the speculum insertion tube port 4 is provided at the lower portion of the mask shell 1, and the lower portion of the mask shell 1 is an elongated region of the mask shell 1, i.e., an end near the forehead, so that the speculum can be operated without obstructing the assisted breathing.

Optionally, the distance between the speculum canula port 4 and the gas inlet 3 varies from speculum anaesthetic mask model to speculum anaesthetic mask model, e.g. as shown in table 1, so that the speculum canula port 4 is as close as possible to the patient's mouth and does not prevent other equipment from being connected to the gas inlet 3.

Optionally, the diameter of the speculum insertion tube opening 4 is different according to different mask models, and optionally, as shown in table 1, the speculum insertion tube opening 4 occupies as small a space as possible, and an endoscope can be conveniently inserted into or taken out of the speculum insertion tube opening 4.

Fig. 4 shows a structural schematic diagram of a sheet-shaped check valve flap arranged inside a speculum insertion tube opening of the speculum anesthesia mask shown in fig. 1, and as shown in fig. 4, a double-layer sheet-shaped check valve flap 6 is arranged in a pipeline of the speculum insertion tube opening 4, so that even if a speculum extends into the mask shell 1 through the speculum insertion tube opening 4, the inside and the outside of the speculum anesthesia mask are kept isolated, namely, the speculum anesthesia mask and the face of a patient can still form a closed space for auxiliary ventilation or controlled ventilation.

Alternatively, as shown in fig. 4, the sheet-like one-way flap valve 6 is a four-flap valve to facilitate the forward and backward operation of the endoscope.

Furthermore, the valve flaps between the double layers of the sheet-shaped one-way flap valves 6 are distributed in a staggered mode, so that air leakage during the placement of endoscopes such as an esophageal ultrasonic probe, a gastroscope, an esophagoscope and a fiberbronchoscope is avoided, and the safety and the effectiveness of auxiliary ventilation or mechanical ventilation are improved.

Optionally, as shown in fig. 2, a sealing ring 7 is provided at the connection between the gas inlet 3 and the mask shell 1, which can be used to fix the mask during the auxiliary/controlled ventilation of the respirator, and prevent the gas introduced into the mask shell from escaping from the gap between the gas inlet 3 and the mask shell 1.

As shown in fig. 2, a fixing hook 8 is further disposed on the sealing ring 7 for hanging a fixing band, and the fixing band is used for fixing the mask on the face of a patient to prevent air leakage.

The following describes a method of using the speculum mask provided in the present application, with a specific example:

for a patient needing sedation or general anesthesia, the endoscope mask can be used for induction, the sealing plug is blocked in the endoscope insertion pipe opening at the moment, the endoscope mask is in a completely airtight state, and endoscopy or operation can be performed after the endoscope mask is prepared.
